摘要：The authors present the prospects of cooperation between transmission system operators (TSO) and distribution system operators (DSO) after entry into force ENTSO-E (European Network of Transmission System Operators for Electricity) grid codes.New areas of DSO activities,associated with offering TSO aggregated services for national power system regulation based on the regulation resources connected to the distribution grid,and services on the distribution system level as part of the creation of local balancing areas (LBA) are presented.The paper also presents the possibilities of providing ancillary services by different types of distributed generation sources in the distribution network.The LBA concept,which involves integrated management of local regulation resources including generation,demand,and energy storage is described.The options of the renewable energy sources (RES) using for voltage and reactive power control in the distribution network with the use of wind farms (WF) connected to the distribution system are characterized.
